A TTORNEYUSZ Application filed August 5,

To all whom it may concern:

Be it lrncwn that l, HERMAN C. Doreen, a citizen of the United States,and resident of Ushlrosh, in the county of Winnebago and State of lJisconsin, have invented new and useful Improvements in WashingMachines, of which the following is a description, refrence being had tothe accompanying drawngs, which are apart of this specification.

present invention relates to certain new nd useful improvements inwashing machines of that type used in washing weara A a el and the like.

the washing machines now in common everyday use, a reciprocating andoscillating dolly is employed which has proven very unsatisfactory inthat it is practically impossible to use the same in connection withfine materials as the dolly often tears the clothing,

Hence with these inherent objections in mincl my invention has for oneoi its ob jects to provide a washing machine in which a plurality ofspray nozzles are employeci, so arranged as to clirect a spray of fiuicltherefrom in a direction to impart the clothes within the washer awhirling movement.

Another object of the present invention is to provide a washing machineof the class clescriheci employing a plurality of spray nozzles soarranged as to impart a whirling movement to the clothes being cleaned;in which the spray from the nozzles will he of sufficient strength toloosen the dirt from the clothes,

A further object of this invention is to provide means for selectivelysupplying fluid to a plurality of spray nozzles so arranged as to importit whirling movement to he clothes being cleaned.

-A still object oi? this invention is to provide means for circulatingthe wcte in the machine through the cleans ing spray nozzles.

A still further object of the present on is to provide it cylinderhaving a re "1Pl'-i) sting piston therein arranged oraw c roni thewashing machine coni rec the same through one of e rality of spraynozzles arrange-cl to dise within the container of he washing chino anclmeans operable upon one coninioveznent of the reciprocating piston connct the port of the cylinmen spray nozzle of the plural- Specification ofLetters Patent.

Figure 2 1s a top plan of tne'wasn mgmachine container, sold container being shown with the usual. coverremoveoi there vfi irons.

Figure 3 is detailed sections.

Figure i is elevational view of plying cylinder, piston reciprccati androtary valve operating means, being taken look ng at the sicle of der tothe right 1th reference and Figure 5 is s top plan view oi ing mechanismfor the reciproc and selectively rot liable valve ing taken on the line5 Referring now moi accompanying draw designates the work con '7 thesupporting legs and 8 a transverse p we ceiving the plying water to thea i er pressure to the adjacent in Figure 2 in. 1 nectecl bycounter-bored end 13 of a cylinder 14 adapted to be secured centrally tothe underside of the bottom wall 9.

Mounted in the counter-bored end 13 is a substantially invertedcup-shaped rotary valve 15 carried by .a valve rod or stem 16,journalled at its lower end in the bearing 17 fixed to the base 8. Thevalve 15 has a single port 18 in its side peripheral wall adapted to beselectively registered with the ends 19 of the pipes 12 communicatingwith the counter-bored end 13. The valve 15 is rotated to selectivelyregister with said ends 19 by means to be later described.

Reciprocally mounted within the cylinder 14 is a piston 20, having itsrod 21 centrally bored and slidably mounted on the valve stem or rod 16,and having its lower end slidably mounted in a packing gland 22, formedcentrally on a cap 23, closing the lower end of the cylinder. The lowerend of the cylinder is in communication with the container or receptacle6 by means of a circulating pipe 24 leading from the bottom of thecontainer, as at 25, and connected with the cylinder, as at 26, the end25 of the pipe being covered by a screening member 27.

The piston 22 is reciprocated, by means to be later described, and inits downward movement a plurality of gravity controlled valves 28carried thereb are operated to allow the water supplie to its undersideby the circulating pipe 24 to pass therethrough, and in its upwardmovement the valves 28 automatically close and the water then on the uper side of the piston is forced through t e ort 18 of valve 15 and outthrough the disc arge jet 11 of the spray nozzle, having its end 19registered with the port 18. The piston in its upper movement creates asuction or vacuum on its under side and draws water into the cylinderthrough circulating pipe 24, in order that in its downward movementthere will be water to pass by the valves 28 as before described.

The iston 20 is r'eciprocated by means of an e ectrical motor 29 ingeared connection with a gear 30 carried by a shaft 31, journalled inbearing 32 and having a crank 33 formed thereon and connected with alever 34 having one end pivoted, as at 35 to a brace 36 carried by arear wall of the container 6, by means of a link 37. The other end ofthe lever 34 is forked to provide a bearing of spaced arms 37 pivotallyconnected to a cross head or bar 38 carried by the lower end of thepiston rod 21. Thus it will be obvious that. by the rotation of thecrank 33 through the medium of the motor 29, the piston 20 will bereciprocated within the cylinder 14.

The valve 15 is rotated one step upon each working stroke of the piston20 so that first one spray nozzle will be coupled with the port 18 uponone upward strokeof the piston, and another upon the next upward strokeof the piston as will be apparent. The means I employ for intermittentlyrotating the valve 15 one step at a time comprises a ratchet wheel 39fixed to the valve stem 16 near its lower end and selectively en ageablewith its teeth 40 is a pivoted'paw or dog 41 carried by a lever 42,having one end freely pivoted on the rod or stem 16 adjacent the ratchetwheel 39, the pawl or dog 41 being normally urged to engage theperiphery of the wheel 39 by means of a flat spring 43. The other freeend of the lever 42 is pivotally connected with the long arm 44 of abell crank lever by means of a link 45, having a pivotally connectionwith the arm 42 and a universal joint connection, as at 46, with thebell crank lever. The bell crank lever is pivoted to a standard 47carried on the base 8 and has its other shorter arm 48 connected to thelever 34 medially of its ends by means of a pivoted link 49.

The bell crank lever 48 is so proportioned and connected with the lever34'so that when the iston 20 is on its upward movement, the 0g or pawl41 will be moved in an anticlockwise direction with respect to Figure 5to en age the pawl behind the next tooth 40, as eplcted in dotted lines,so that upon its downward movement the pawl 41 will rotate the ratchetwheel one tooth in a clockwise direction to position or register theport 18 with the end 19 of the next spray nozzle.

In order to prevent the valve 15 from being rotated in anti-clockwisedirection when the pawl'41 is riding over the next tooth, by thefriction thereagainst the ratchet wheel caused by its spring 43, Iprovide a plurality of notches on recesses 50 in the side wal of thevalve 15 so arranged that when the port 18 is registering with the end19 of any one pipe 12, one of the notches will be engaged by a springoperated ball or check 51 carried by the adjacent portion of thecounter-bored end 13, as at 52, see Figure 3.

- The check or ball 51 prevents the accidental movement of the port 18from registering with its adjacent pipe end 19.

As best shown in Figures 1 and 2, the sharp corners of the container 6are relieved by inclining them, as at 6, so that no resistance will beoffered to the clothes in their whirling movement. The jets 11 are soarranged that the sprays 11 ejected therefrom will be upwardly at anangle from the bottom 6 and towards the adjacent spray nozzle 10 wherebya whirling movement will be imparted to theclothes within the container6 by the sprays 11. The sprays 11' take the place of the reciprocatingor oscillating dolly now gen ally emoloyed in washing machines and espray is oil "force to play upon the c othes penetrating thcrethrough,which gether the whirling movement of the othes thoroughly cleanses thesame,
